If the probability that A will live 15 years is 78 and that B live 15 years is 910, then what is the probability that both will live after 15 years?

The correct option is B 6380P(A) = 78P(B) = 910Since both of them are independent events hence, probability of both living 15 years = P(A)⋅P(B) = 78×910 = 6380

If the probability that $A$ will live $15$ years is $\frac{7}{8}$ and that $B$ live $15$ years is $\frac{9}{10}$ , then what is the probability that both will live after $15$ years?

The correct option is B $\frac{63}{80}$
P(A) = $\frac{7}{8}$
P(B) = $\frac{9}{10}$
Since both of them are independent events hence, probability of both living 15 years = $P (A) \cdot P (B)$ = $\frac{7}{8} \times \frac{9}{10}$ = $\frac{63}{80}$
